New Horizons has now been able to image all of Pluto’s known moons.

Pluto’s five known satellites are Charon, Hydra, Nix, Kerberos and Styx. At 648 miles (1,043 km) in diameter, Charon is nearly half as wide as Pluto itself, but the other four moons are minuscule. Kerberos and Styx, for example, are thought to be just 4 to 13 miles (7 to 21 km) and 6 to 20 miles (10 to 32 km) wide, respectively.

That the spacecraft has been able to spot them all this soon bodes well for what it will see when if flies past Pluto in July.
